- Contains 60% Potash (K).
- By far the most widely used K fertilizer.
- Available in white and reddish crystalline form.
- Readily dissolves in water
- On application to soil, it ionizes to dissociate into K & Cl ions. K gets attached or adsorbed on the soil
complex. As such, though MOP is readily soluble in water, it is not leached.
- High concentration of nutrients makes packing, storage and transport costs per unit cost of nutrient very low.
